# Brian Sparker

> Product leader with 10+ years building teams and scaling consumer apps at the intersection of product, growth, and emerging technology. Former You.com product manager focused on AI, search, and developer platforms. MBA from Boston University Questrom School of Business.

Brian Sparker operates in complex, cross-functional environments — partnering with engineering, design, sales, marketing, and leadership to turn fuzzy ideas into concrete systems that ship and scale. Recurring themes in his work include distribution, pricing, packaging, and how AI products should be priced, constrained, and explained so users trust them. He is deeply hands-on: prototyping, writing PRDs, pressure-testing assumptions, and building lightweight tools to validate ideas quickly.
